Reasoning for sorting is, the "leveling up" of the girls. For example, for me currently (= at this very moment while writing this)
Felicia has with lvl 5956 damag of 784.78E3 (most damage output of all girls)
Lupa has with lvl 5963 damage of 503.17E3
(both girls are "idle girls" as is bunny) Other girls with the same amount of leveling have only xxxE1 damage which is completely irrelevant.
So for current upgrading, I want Felicia and Lupa next to each other, because I'm only leveling these two
In other words, powerfull ist in my current situation not relative. It is a measurable absolut value. And I would like to sort these girsl by that value
Keep in mind, this is only a convenience thing I'm asking for. It makes the leveling quicker and I can get more "resets" done per play session.
